Peat-fuel machine



Filed Aug. 16, 1927 Patented Dec. 10, 1929 UNITE FEAT-FUEL MACHINEApplication filed August 16, 1927. Serial No.. 212,939.

This invention relates to peat fuel and has special reference to a novelform of machine for making same.

I have discovered that a unit of fuel in form representing a pluralityof initially united hollow cylinders is an ideal form both as respectscheapness of manufacture, and efficiency and convenience in consumption,and the object of my present invention is to provide simple means forproducing such units of fuel.

Other objects and advantages of the invention will appear in the furtherdescription thereof.

Referring now to the accompanying drawing, forming part of thisapplication, and

wherein like reference characters indicate like parts:

Figure 1 is a front elevation of an improved shape of die for formingthe desired fuel;

Figure 2 is a central vertical section on the line 22, Figure 1 showingin addition the outboard end of a screw feeding device to which the dieis attached;

Figure 3 is a perspective view of one of the initially formed units offuel; and

Figure 4 is a like view of the ultimate unit of fuel, being a fragmentalportion of the unit shown in Figure 3.

1 represents the discharge end of a common screw or auger feeding devicesuch. as commonly used in brick making or the like, to which is appliedmy improved die, and this I prefer to form in two sections 2 and 3,

the former being bolted as at t directly to the end of the augerdischarge housing and the latter removably attached as by the bolts 5 tothe face of the former, this being particularly for convenience inassembling or examining the interior of the die.

Recessed within the innermost shoulder of the section 2 of the die isthe inverted T- shaped spider 6 for the support of the cylindrical cores7 which extend forwardly of the end and preferably entirely through thedie. There are four of these cores, one axially of the die and the otherthree spaced equally radially therefrom and axially of the threecircular discharge orifices of the die, this being the preferred formfor the results hereinafter explained. I will subsequently refer forconvenience to the shape as being multiple lobe and both the receivingand discharge ends of the die are of this form, the former being inoutside diameter substantially equalto the bore of the discharge end ofthe auger casing, and the angle of the walls of the die I have learnedby experiment to give best results'if formed at an angle not to exceed30 from the axis of the die, thus resulting in a multiple lobe die whoseplanes take the shape of a multiple truncated cone.

Upon the extreme outer or discharge end of the die is attached as at 8 ashort sleeve or extension 9 which in cross section is the same shape andsize as the discharge end of the die so that the product as formed bythe latter when passing therethrough is carried horizontally for a shortdistance to improve the external walls of same before being final- 7 lycut into any desired length by a common wire cutter not shown.

In Figure 3 I have shown a section or portion of the product as it comesfrom the machine ready for drying either artificially or 7 naturally,and as is obvious the product may be cut as desired and is in the formof three more or less delicately attached hollow cylinders which whensubsequently handled are subject to fracture and found frequentlyseparated into the form shown in Figure 4 which is the desired ultimateproduct.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1 A die for forming peat fuel units comprising a multiple lobe truncatedcone, andv a core axially of each lobe.

2. A peat fuel die comprising a truncated cone whose'b'ore is ofmultiple lobe shape in cross section, and spaced cores centrally of saidbore, one of said cores being axially of the cone and the others axiallyof the lobes.

3. A die for forming peat fuel multiple lobe units comprising atruncated cone and a cylindrical core axially of each lobe of the unitfor forming a uniform thickness of lobe walls for the purpose described.

In testimony whereof I afiix my signature.
